The Red Wings attacked first in the overtime but got a bad bounce off an official near the blue line to send the Bruins off on a rush. Marchand picked up a rebound off Krug’s shot, moved it to his backhand and scored the winner, triggering an avalanche of the free green hats given out in honor of Irish Heritage Night.

“Most nights it’s not going to be 6-5,” Bruins coach Bruce Cassidy said. “But when it is, the guys have got to know they’ve got a chance to get it done. That is a good quality to have in your group. You don’t want to use it every night.”

It was the 600th meeting between the two Original Six teams. Detroit holds a 251-250-95-4 edge, but Boston has gone 14-1-1 in the last 16 games. … It was Irish Heritage Night, and the Bruins practice jerseys were green with plaid trim. Irish step dancers and musicians were featured in the concourse and vomitoria. … Coreau made his first NHL appearance of the season after being named the AHL goaltender of the month in February.

The Panthers are two points out of the final playoff spot in the East. They are 19-9-3 at home and are coming off a game in which Nick Bjugstad scored his first career hat trick.

“Bjugstad was a monster,” Panthers rookie coach Bob Boughner told the media. “He was taking pucks to the net and dragging people on his back.

“Since I have been here, that was the best game I’ve seen him play.”

Bjugstad was humble about his hot streak, which includes 16 points in his past 16 games.

“It was just one of those games where the puck was finding my stick,” he said. “It feels good. It would’ve been better with a win, but that’s a good team (Tampa Bay).”

Montreal, meanwhile, has slumped badly this season, dragged down by a 9-20-3 road record.

“It’s never fun to be in a losing atmosphere,” Montreal forward Andrew Shaw told the media after his team fell behind 4-0 to the Devils in a 6-4 loss on Tuesday night. “Personally, it’s been tough. But it’s been tougher on the team.
